Video File Corrupted

I just finished editing a video from final cut pro x on my mac and i wanted to transfer it to my Samsung Galaxy S7 so i could share it on instagram. I tried about three different methods to get it onto my phone. One was using Android Transfer File, another was Portal by pushbullet, and the last was just removing my micro SD card, putting it in an adapter to SD, and putting it into the slot of my mac. They all came to the same result. There was no sound in the video and instagram and other programs said the video was corrupted. It plays fine on my mac. I have no idea why this is happening. Help please.
